2. Chapter 9: Lesson 1 1. What is the formula for finding density? Density = mass / volume 2. Describe the steps to find the density of a cube. 1. Finding the mass of the object 2. Finding the volume of the object 3. Dividing the mass by the volume. Density = mass / volume

3. 3. How does the density of an object determine whether or not it floats? If an object is more dense than water it will sink. If an object is less dense than water it will float. 4. What is the name of the instrument at the bottom of the page? Graduated Cylinder

8. 10. Describe the physical properties (their volume and shape) of the states of matter: Solid: definite shape, definite volume Liquid: definite volume, not a definite shape - Liquids will take the shape of their container Gas: not a definite shape or volume - Gases change shape and volume to fill any container

9. 11. A) 8 ounces of water will boil at 100°C. At what temperature will 1,800 ounces of water boil at? 100°C B) Why? Water will always boil at 100°C, regardless of the amount of water.

10. 12. What happens to the amount of mass in an object when it goes from a solid to a liquid or from a liquid to a gas? The amount of mass does not change. (Matter is neither created or destroyed.) 13. Name some physical properties used to describe a rock. Any property that can be observed without changing the identity of the substance: Density, odor, hardness, color, shine, shape, texture

11. 14. A) What is a physical change? Changing something without changing the substance B) Give an example of a physical change. Melting, Boiling, Freezing
